Thisproject integrates Internet, multiple databases, remote sensing, and other visualization technologies. The resultcombines a GIS database with other visualization system called Bridge Web-based, GIS Integration (Bridge-WGI),developed for evaluating and maintaining the national bridge information system (NBIS). Web-GIS based applicationincorporates national bridge inventory (NBI) data, remote sensing data generated by LiDAR scans, small format aerialphotography (SFAP), and decision-making support modules, into a general framework with a user-friendly interfaceand easy Internet accessibility.The guiding objective of this analytical tool is to enhance the capability of the National Bridge Inspection System(NBIS) through:1) providing a better interpretation of bridge condition information;2) providing a decision support module for bridge maintenance;3) providing data entry and visualization functionalities for various information (text, image, and documents); and4) providing a report generating tool for easier to interpret bridge information.Bridge-WGI captures all the conventional functionalities of a Web 2.0 application. With Bridge-WGI, there is acapability for Bridge Management Systems (BMS) to migrate into an open architecture, secured access, and robustinteractivity. Benefitting from Internet interactivity, Bridge-WGI is another step toward \ue2\u20ac\u153anytime anywhere\ue2\u20ac? globalconnectivity objectives. Interactive visualization provide various data interpretations including general bridgeinformation, visual analytics, bridge condition distribution mapping, statistical graphs, conditional bridge search, pre-caution alarm, and maintenance decision support. A bridge data tablet application helps bridge inspectors input bridgedata easily via the Internet
